Description

자외선 및 청색광 차단 기능성 안경렌즈{Functional glasses lens having Fuction of Blocking UV Light And Blue Light}[0001] The present invention relates to a functional lens having a function of blocking UV light and blue light,

본 발명은 자외선 및 청색광 차단 기능성 안경렌즈로서, 이를 보다 상세히 설명하면 인체 및 인체 중 눈에 극히 해로운 자외선 영역의 파장과 단파장 영역의 파장인 청색광을 함께 차단할 수 있도록 하여 자외선 및 청색광으로 인한 눈부심과 피로감 및 눈병 등을 예방할 수 있는 효과를 제공토록 한 자외선 및 청색광 차단 기능성 안경렌즈에 관한 것이다.The present invention relates to an ultraviolet and blue light blocking functional spectacle lens. More specifically, the present invention relates to a spectacle lens for blocking ultraviolet rays and blue light, which can shield both the wavelength of ultraviolet rays, which are extremely harmful to the eyes of the human body and the human body, And to provide an effect of preventing eye diseases and the like.

일반적으로 가시광선(visible light, 可視光線)의 녹색 및 적색부분과 적외선 및 마이크로파, 라디오파 등의 파장이 긴 전자파는 인체, 특히 눈에 크게 유해하지 않으나, 가시광선의 자색 내지 푸른색부분의 청색광이나 자외선 및 X선, 감마선 등의 파장이 짧은 전자파의 경우에는 인체에 극히 유해한 영향을 끼치게 되는바, 상기 X선이나 감마선의 경우 태양광 등과 같은 일반적인 자연광에 포함되어 있지 않으므로 주변에 접근하지 않으면 인체에 유해한 영향을 받을 경우가 거의 없으며, 100~280nm의 UV-C와 280~320nm의 UV-B는 대기의 오존층에서 거의 흡수되고 있으며, 흡수되지 못한 UV-B 일부와 320~400nm의 UV-A는 오존층에서 흡수되지 못하고 지면으로 내리 쬐이고 있었으며, 최근 대기오염으로 인한 오존층의 파괴로 인하여 다량의 자외선이 지상에 도달하여 인체에 대한 유해성이 높아지고 있으며, 상기 380nm이하 및 380~400nm의 파장을 갖는 자외선(ultraviolet) 및 상기 자외선과 겹치면서 가시광선 내에서 푸른빛을 내는 380~500nm의 파장을 갖는 청색광(blue light)이 햇빛에 포함되어 있어서 인체 중 특히 눈의 보호를 위해서는 자외선 및 청색광을 차단하는 안경 등을 착용함이 이로우며, 이러한 자외선을 차단하는 선글라스나 자외선 전용 차단렌즈가 다수 개발되어 왔으며, 특히 청색광은 자외선에 비하여 위험성이 낮은 것으로 인식되어 있으나, 이러한 청색광은 일명 단파장(short wavelength, 短波長)이라고도 하는바, 파장이 짧아 망막의 앞쪽에 맺혀서 정확한 상으로 인식되지 않으므로 색이 분산되기 때문에 눈의 피로감을 유발시키며, 또한 파장이 짧을수록 에너지가 높아지는데 그만큼 눈에 있는 시세포(視細胞)를 강하게 자극해서 눈부심과 함께 눈의 피로감을 더욱 가중시키게 되는 문제점을 가지고 있었으며, 근자에 널리 보급되고 TV, 컴퓨터 모니터, 스마트폰, 태블릿PC, 휴대용 게임기 등의 디스플레이에는 해상도를 높이기 위해 광원으로 빛이 밝은 CCFL(cold cathode fluorescent lamp, 냉음극 형광 램프) 또는 LED(light emitting diode) 등을 사용하며, 이러한 CCFL이나 LED 등은 빛이 밝은 대신에 그 만큼 많은 청색광이 포함되어 있으므로 현대인들의 시력이 예전에 비하여 급격히 저하될 수밖에 없는 실정이었다.Generally, green and red portions of visible light and electromagnetic waves of long wavelengths such as infrared, microwave, and radio wave are not harmful to human body, especially eye, but blue light of purple or blue portion of visible light In the case of electromagnetic waves having a short wavelength such as ultraviolet rays, X-rays and gamma rays, they have an extremely harmful effect on the human body. In the case of X-rays and gamma rays, they are not included in general natural light such as sunlight. UV-C of 100-280 nm and UV-B of 280-320 nm are almost completely absorbed in the ozone layer of the atmosphere. The part of the UV-B not absorbed and the UV-A of 320-400 nm The ozone layer has not been absorbed and has been sunk down to the ground. Due to the recent destruction of the ozone layer due to air pollution, a large amount of ultraviolet light reaches the ground, Ultraviolet rays having a wavelength of 380 nm or less and a wavelength of 380 to 400 nm and blue light having a wavelength of 380 to 500 nm which overlaps with the ultraviolet ray and emit blue light in the visible light are included in the sunlight In order to protect the eyes of the human body, particularly, glasses for shielding ultraviolet rays and blue light are worn. Many sunglasses or ultraviolet ray blocking lenses for blocking ultraviolet rays have been developed. In particular, However, such a blue light is also referred to as a short wavelength (short wavelength). Since the wavelength is short, it is not recognized as an accurate image because it is formed on the front side of the retina, and thus the color is dispersed. The shorter the energy is, the higher the visual cells in the eye Which is widely used in TVs, computer monitors, smart phones, tablet PCs, portable game machines, and the like, has a problem in that it has a problem in that the light source is CCFL (cold cathode fluorescent lamps) or LEDs (light emitting diodes) are used. Since CCFLs, LEDs, and the like contain a lot of blue light instead of light, modern people's eyesight is rapidly It was inevitable that it would deteriorate.

이에 상기와 같은 인체 및 눈에 유해한 자외선 내지 가시광선 내의 청색광을 반사 및 흡수하여 눈을 보호토록 한 기술이 개발되고 있으며, 종래 자외선 내지 청색광을 차단 및 흡수하기 위한 렌즈 또는 안경에 관한 기술로는 하기 선행기술문헌의 대한민국 특허공개 1988년 제7001894호(1988년 11월 5일자 공개)에서와 같이 렌즈를 제조할 시 컷-온 필터가 통합된 편광필름을 부착하거나 이를 착색 염료에 고온에서 침지시켜서 자외선 및 청색광을 흡수하거나, 대한민국 등록실용신안 제230630호(2001년 7월 19일자 공고)에서와 같이 안경의 렌즈표면에 자외선의 양에 따라 색상 및 색 농도가 변하는 은과 할로겐원소를 포함한 플라스틱 레진막 또는 편광필름을 단독 및 복합적으로 형성하여 자외선 및 단파장의 가시광선을 흡수 및 차단하도록 하였으나, 이러한 종래 기술들은 렌즈자체에 색상을 부여시켜서 자외선과 가시광선 내의 단파장인 청색광을 흡수토록 한 것이므로 렌즈의 편광필름 부착과 염료에 의한 착색에 의해서 자외선 및 청색광 외의 인체에 유해하지 않은 가시광선까지도 흡수하게 되어 원래의 색상 그대로 보이지 않고 색상 및 색 농도의 변화가 많았으며, 특히 가시광선에서 청색광을 제외한 인체에 유해하지 않은 녹색 내지 적색부분인 500~780nm의 파장을 갖는 장파장의 투과율도 함께 저하시키게 되므로 안경이나 콘택트렌즈로 제작하여 사용할 시 이를 장기간 착용하거나 탈착을 자주 반복하게 되면 시력을 급격히 저하시키는 원인이 되는 문제점을 가지고 있었으며, 상기 렌즈에 부착된 편광필름의 경우 잦은 박리와 스크래치가 발생되며, 렌즈의 착색에 사용되는 염료의 경우 취급상 유의할 점이 많으며, 염료를 렌즈에 착색할 시 규격화된 색상의 농도를 가지는 렌즈의 제작이 무척이나 곤란하므로 제작상의 다양한 문제점을 가지고 있었던 것이다.Techniques for protecting and protecting the eyes by reflecting and absorbing the blue light in the ultraviolet rays or visible rays harmful to the human body and the eyes have been developed. Conventionally, as a technique relating to a lens or glasses for blocking and absorbing ultraviolet rays or blue rays, As described in Korean Patent Publication No. 7001894 (published on Nov. 5, 1988) of the prior art, when attaching a polarizing film incorporating a cut-on filter in the manufacture of a lens or immersing it in a colored dye at a high temperature, And a plastic resin film containing silver and halogen elements whose color and color density are changed according to the amount of ultraviolet rays on the lens surface of the glasses as in Korean Utility Model No. 230630 (published on Jul. 19, 2001) Or polarizing film alone or in combination to absorb or block visible light of ultraviolet and short wavelengths, Technologies are designed to absorb color of ultraviolet light and blue light which is short wavelength in visible light by attaching color to the lens itself. Therefore, by attaching polarizing film of lens and coloring by dye, visible light which is not harmful to human body other than ultraviolet ray and blue light is absorbed And the transmittance of a long wavelength having a wavelength of 500 to 780 nm which is a green to red part which is not harmful to the human body except blue light in a visible light is also lowered in the visible light as well. The polarizing film attached to the lens has frequent peeling and scratches. When the polarizing film attached to the lens is frequently used, Handling Considerations for Dyes Used Often, since the production of a lens having a concentration of the normalized color to color when the dye to the lens is very difficult or could have a variety of problems in production.

또한 대한민국 공개특허 2013년 제85415호(2013년 7월 29일자 공개)에 게재된 바와 같이 종래 자외선 내지 청색광을 차단하는 렌즈가 갖는 문제점을 해결코자 플라스틱 기재의 표면에 고굴절률 재료와 저굴절률 재료가 복수로 적층된 다층막이 구비되며, 플라스틱 기재와 다층막 사이로 기능성 박막 등이 적층되도록 구성한 기술이 공지되어 있었으나, 이러한 구성을 갖는 렌즈는 제작이 어렵고 시간이 오래 걸리는 등으로 해서 제조원가가 높아지는 등의 문제점을 가지고 있었던 것이다.In order to solve the problems of conventional lenses blocking ultraviolet light or blue light as disclosed in Korean Patent Publication No. 85415 (published on Jul. 29, 2013), a high refractive index material and a low refractive index material There has been known a technique in which a plurality of multilayered films are laminated and a functional thin film or the like is laminated between a plastic substrate and a multilayer film. However, a lens having such a structure has problems such as difficulty in manufacturing, I had it.

상기와 같이 근자에 들어서 자외선과 청색광을 함께 차단하는 기능성 안경렌즈가 지속적으로 개발되고 있었으나, 대부분의 렌즈가 380nm이하의 단파장대 자외선은 효과적으로 차단하고 있었으나, 380~400nm의 장파장대 자외선의 흡수성능은 현저히 떨어져서 380~400nm의 자외선 투과성이 높고, 이로 인하여 눈에 유해한 문제점이 있었으며, 이러한 자외선에 더불어 청색광을 차단시키도록 렌즈를 제조하면 렌즈 자체가 노란색을 띄게 되어 자연광이 눈에 왜곡되어 보이게 되는 등의 문제점도 함께 가지고 있었던 것이다.As described above, a functional spectacle lens that blocks both ultraviolet and blue light in the near future has been continuously developed. However, most of the lenses effectively block the short-wavelength ultraviolet rays of less than 380 nm, but the absorption performance of long wavelengths and ultraviolet rays of 380 to 400 nm The ultraviolet ray transmittance of 380 to 400 nm is remarkably high and thus it is harmful to the eyes.
